Amphenol Piher PT-10 Carbon Potentiometers

Amphenol Piher PT-10 Carbon Potentiometers feature a carbon resistive element and polyester substrate in a dust-proof enclosure with life up to 10,000 cycles. The PT-10 potentiometers operate where frequent adjustment is required, and control variable outputs including frequency, motor speed, and volume. These Amphenol Piher carbon potentiometers come with a shaftless design that allows for different engagement mechanisms such as a customized shaft, motor, or human interface adjustment. The PT-10 potentiometers offer mechanical detents, 3% linearity and 100K cycles, self-extinguishable plastic UL94V-0, and low torque version upon request. These 10mm carbon potentiometers come in vertical mounting with horizontal adjustment and horizontal mounting with vertical adjustment.

Amphenol Piher PT-10 Carbon Potentiometers feature 1000 hours of electrical life at 50°C and 1000 cycles of mechanical life. These PT-10 potentiometers operate in a -25°C to 70°C temperature range. Typical applications include test and measurement equipment, consumer electronics, appliances, small engines, and medical equipment control panels.
